- 0.72u1: Misc improvements, cleanups and fixes to the B-Wings driver [Acho A. Tang]. Known issues: The main program is responsible for sprite clipping but occational glitches can be seen at the top and bottom screen edges (post rotate). B-Wings bosses sometimes flicker (sync issue). The text layer has an unknown attribute (needs verification). Zaviga's DIPs are incomplete (manual missing). Changed description of clone 'Battle Wings (alternate)' to 'Battle Wings (alt)'.
